A few of us did use the factory white power lead when installing the etrailer harness. The factory power lead is protected by a 30amp fuse under the hood. We then installed a 20amp in the back as well. This way if compromised it would pop prior to ever overloading the factory wiring/circuit etc.
Well done on your own install! This is definitely one of those that anyone with a few tools could easily save some money on.
